Testing - Manual, Automation and Performance - Which is great?

Manual deals with more of test cases,

Executing them on the application, reporting bugs...

Automation deals with more of scripting,

Changing the test case to a test script, test suite execution on the application - again final aim is to find bugs…

Performance deals with more of Server Response Times,

Load testing, Stress testing, Monitoring - again to find out performance violations...

There cannot be Automation without Manual Testing (Test Cases),

There cannot be Manual Testing without Performance (availability of the application for testing)

And there cannot be Performance Testing without automating! (Scripting)
